The result is the same with 2.4 or 2.6 kernel headers. I doubt I need DirectFB for anything, but it prevents emerge -u world from proceeding. Reproducible: Always Steps to Reproduce: 1.

This is a compiler bug, gcc simply runs out of registers. Workarounds in order - removing "mmx" from USE flags during emerging this - Play around with the CFLAGS, e.g. changing -O2 to -O1 has worked somewhere else - Change gcc version
Removing mmx USE flag "solved" this problem for me. Thanks Roland!
